Scrapping of your Toyota
The SRS airbag and seat belt pretensioner devices in your
Toyota contain explosive chemicals. If the vehicle is
scrapped with the airbags and pretensioners left as they
are, it may cause an accident such as fire. Be sure to
have the systems of the SRS airbag and seat belt preten-
sioner removed and disposed of by a qualified service
shop or by your Toyota dealer before you dispose of your
vehicle.
On–pavement and off–road
driving tips
This vehicle belongs to the utility vehicle class. Utility ve-
hicles have a significantly higher rollover rate than other
types of vehicles. This vehicle will handle and maneuver
differently from an ordinary passenger car because it is
designed for off–road use also. In addition, this vehicle
has a higher ground clearance and center of gravity than
that of an ordinary passenger car. This vehicle design fea-
ture causes this type of vehicle to be more likely to rol-
lover. Failure to operate this vehicle correctly may result in
loss of control, accidents or vehicle rollover causing death
or serious injury. Be sure to read “Off–road vehicle precau-
tions” on page 240 in Section 2 and “Off–road driving pre-
cautions” on page 259 in Section 3.

Your vehicle is supplied with the two
kinds of keys.
1. Master keys (black)—These keys work
in every lock. Your Toyota dealer will
need one of them to make a new key
with built–in transponder chip.
2. Sub key (gray)—This key does not
work in the glove box.
A transponder chip for engine immobiliser
system has been placed in the head of
the master and sub keys. These chips are
needed to enable the system to function
correctly, so be careful not to lose these
keys. If you make your own duplicate key,
you will not be able to cancel the system
or start the engine.
To protect items locked in the glove box
when using valet parking, leave the sub
key with the attendant.
Since the side doors can be locked with-
out a key, you should always carry a
spare key in case you accidentally lock
your keys inside the vehicle.
NOTICE
When using a key containing a trans-
ponder chip, observe the following
precautions:
 When starting the engine, do not
use the key with a key ring resting
on the key grip and do not press
the key ring against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts.

2003 4RUNNER from Oct. ’02 Prod. (OM35804U)
 When starting the engine, do not
use the key with other transponder
keys around (including keys of oth-
er vehicles) and do not press other
key plates against the key grip.
Otherwise the engine may not start,
or may stop soon after it starts. If
this happens, remove the key once
and then insert it again after taking
off other transponder keys (includ-
ing keys of other vehicles) from the
ring or while gripping or covering
them with your hand to start the
engine.
 Do not bend the key grip.
 Do not cover the key grip with any
material that cuts off electromagnet-
ic waves.
 Do not knock the key hard against
other objects.
 Do not leave the key exposed to
high temperatures for a long period,
such as on the dashboard and hood
under the direct sunlight.
 Do not put the key in water or
wash it in an ultrasonic washer.
 Do not use the key with electromag-
netic materials.

KEY NUMBER PLATE
Your key number is shown on the plate.
Keep the plate in a safe place such as
your wallet, not in the vehicle.
If you should lose your keys or if you
need additional keys, duplicates can be
made by a Toyota dealer using the key
number.
We recommend writing down the key num-
ber and storing it in a safe place.
The engine immobiliser system is a
theft prevention system. When you in-
sert the key in the ignition switch, the
transponder chip in the key’s head
transmits an electronic code to the ve-
hicle. The engine will start only when
the electronic code in the chip corre-
sponds to the registered ID code for
the vehicle.
The system is automatically set when the
key is removed from the ignition switch.
The indicator light will start flashing to
show the system is set.
If any of the following indicator conditions
occurs, contact your Toyota dealer.
The indicator light stays on except
when the theft deterrent system is set-
ting or activating. (See “Theft deterrent
system” on page 31 in this section.)
The indicator light does not start flash-
ing when the key is removed from the
ignition switch.
The indicator light flashes unsteady.

2003 4RUNNER from Oct. ’02 Prod. (OM35804U)
Inserting the registered key in the ignition
switch automatically cancels the system,
which enables the engine to start. The
indicator light will go off.
For your Toyota dealer to make you a
new key with built–in transponder chip,
your dealer will need your key number
and master key. However, there is a limit
to the number of additional keys your
Toyota dealer can make for you.
If you make your own duplicate key,
you will not be able to cancel the sys-
tem or start the engine.
NOTICE
Do not modify, remove or disas-
semble the engine immobiliser sys-
tem. If any unauthorized changes or
modifications are made, the proper
operation of the system cannot be
guaranteed.
